Description

Technical Field

[0001] This application relates to the field of gas meter technology, specifically to an anti-tamper and anti-theft IoT smart gas meter. Background Technology

[0002] The Internet of Things (IoT) smart gas meter is a gas metering device that integrates IoT technology. Through remote data transmission and interaction, it enables intelligent management of gas usage, which can significantly improve the management efficiency of gas companies, while enhancing user experience and increasing safety.

[0003] A search revealed a patent with publication number CN219178645U that discloses a novel anti-tamper mechanism for a smart gas meter. This mechanism is located at the connection between the upper and lower covers of the gas meter and includes a base and a cover that snap together to form a cavity. The base is positioned on the lower cover, and the cover is positioned on the upper cover. The base has an internal cavity, and a locking seat is located in the center of the base. This invention is installed inside the gas meter cover, making the structure undetectable from the outside and difficult to damage or remove. Furthermore, it features both IoT command and IC card identification methods for controlling the anti-tamper structure, facilitating operation by maintenance personnel.

[0004] The above-mentioned solution achieves a relative concealment of the smart gas meter in terms of structure, making it difficult to detect. However, when criminals learn about the concealed design of the smart gas meter, all such smart gas meters are no longer safe. Criminals can forcibly remove the gas meter by disassembling the expansion bolts that install the gas meter, thereby stealing it. Utility Model Content

[0005] In view of this, the purpose of this utility model is to address the shortcomings of the prior art by proposing an anti-tamper and anti-theft IoT smart gas meter to solve the problems existing in the prior art.

[0006] To achieve the above objectives, this utility model provides an anti-tamper and anti-theft IoT smart gas meter, including an embedded plate. A wall-mounted box is fixedly connected to the outer surface of the embedded plate. A mounting base is detachably installed on the outer surface of the wall-mounted box. The gas meter body is fixedly installed on the mounting base. An expansion sleeve is fixedly installed on the side of the wall-mounted box away from the embedded plate. An expansion screw is threaded onto the inner surface of the expansion sleeve. An elastic limit alarm mechanism is provided inside the wall-mounted box. The embedded plate is installed inside the wall, and the expansion screw can be rotated to a suitable position within the expansion sleeve to stabilize the mounting base on the wall-mounted box, thus achieving the effect of stable installation of the smart gas meter.

[0007] Preferably, the elastic limit alarm mechanism includes a fixed plate fixedly installed on the inner side of the embedded plate. The fixed plate has an electrical connection recess on the side away from the wall box, and the number of electrical connection recesses is four. The elastic limit alarm mechanism can make the expansion screw and expansion sleeve play an alarm function when they are disconnected, thereby effectively stopping the illegal behavior of criminals.

[0008] Preferably, a fixing cylinder is fixedly connected to the end of the fixing plate away from the electrical connection recess, and four sets of fixing cylinders are provided, with fixing rings fixedly connected to the inner walls of the four sets of fixing cylinders.

[0009] Preferably, an insulating rod is fixedly inserted through the inner side of the fixing ring, and a sliding plate is fixedly connected to one end of the insulating rod near the expansion screw, and the outer surface of the sliding plate is slidably connected to the inner wall of the fixing cylinder.

[0010] Preferably, a spring is movably sleeved on the outer surface of the insulating rod, and an electrical connecting piece is provided at the end of the insulating rod away from the slider.

[0011] Preferably, a power supply is fixedly installed on the wall-mounted box, and the power supply is electrically connected to the electrical connector and the electrical connector recess, and a buzzer is electrically connected to the top of the power supply.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This tamper-proof and anti-theft IoT smart gas meter will immediately trigger the internal anti-theft system when criminals attempt to remove the expansion screws. Since the end of the expansion screw no longer presses against the sliding plate, the spring will quickly return to its original position, pushing the sliding plate forward. This, in turn, moves the insulating rod and electrical connector, connecting the circuit. Once the circuit is connected, the buzzer will immediately emit a piercing alarm sound. This not only effectively deters criminals from stealing but also attracts the attention of those nearby, increasing the risk of being discovered and apprehended.

[0014] 2. This tamper-proof and anti-theft IoT smart gas meter uses the collaborative work of multiple mechanical and electronic components to ensure the reliability and stability of the anti-theft system. Even under high-intensity external force, as long as the expansion screw is removed, the anti-theft system can respond quickly. Attached Figure Description

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] Please see Figure 1-4 A tamper-proof and anti-theft IoT smart gas meter includes an inner panel 1, a wall-mounted box 2 fixedly connected to the outer surface of the inner panel 1, a mounting base 3 detachably installed on the outer surface of the wall-mounted box 2, a gas meter body 4 fixedly installed on the mounting base 3, an expansion sleeve 5 fixedly installed on the side of the wall-mounted box 2 away from the inner panel 1, an expansion screw 6 threaded onto the inner surface of the expansion sleeve 5, and an elastic limit alarm mechanism is provided inside the wall-mounted box 2.

[0022] Through the above technical solution, during the installation process, the smart gas meter uses an expansion sleeve 5 and an expansion screw 6 to stably install the mounting base 3 on the wall-mounted box 2. If the expansion screw 6 is screwed out of the expansion sleeve 5, the gas meter body 4 on the mounting base 3 will be removed. During this process, in conjunction with the elastic limit alarm mechanism, a piercing alarm sound can be generated when the expansion screw 6 is forcibly screwed out of the expansion sleeve 5, so as to stop the operation.

[0023] Specifically, the flexible limit alarm mechanism includes a fixed plate 7 fixedly installed inside the inner panel 1. The fixed plate 7 is provided with an electrical connection recess 14 on the side away from the wall box 2, and the number of electrical connection recesses 14 is four.

[0024] Through the above technical solution, the four sets of electrical connection recesses 14 correspond to the corresponding electrical connection pieces 13 and the fixed cylinder 8 and its internal components, so that an alarm effect will be generated after any set of expansion screws 6 and expansion sleeves 5 are separated.

[0025] Specifically, a fixing cylinder 8 is fixedly connected to the end of the fixing plate 7 away from the electrical connection recess 14, and four sets of fixing cylinders 8 are provided. The inner walls of the four sets of fixing cylinders 8 are all fixedly connected to fixing rings 9.

[0026] With the above technical solution, the fixing cylinder 8 is directly facing the corresponding expansion screw 6, and the design of the fixing ring 9 is to cooperate with the spring 12 to adjust the position of the slider 11 (the displacement of the slider 11 comes from whether the expansion screw 6 is properly installed on the expansion screw sleeve 5. If it is properly installed, then the end of the expansion screw 6 near the slider 11 is in contact with and abuts against it).

[0027] Specifically, an insulating rod 10 is fixedly inserted through the inner side of the fixing ring 9, and a sliding plate 11 is fixedly connected to one end of the insulating rod 10 near the expansion screw 6, and the outer surface of the sliding plate 11 is slidably connected to the inner wall of the fixing cylinder 8.

[0028] Through the above technical solution, the insulating rod 10 moves through both the fixed plate 7 and the electrical connection recess 14 simultaneously, and the insulating rod 10 can move laterally during the process of passing through the electrical connection recess 14.

[0029] Specifically, a spring 12 is movably sleeved on the outer surface of the insulating rod 10, and an electrical connecting piece 13 is provided at the end of the insulating rod 10 away from the slider 11.

[0030] Through the above technical solution, the two ends of the spring 12 are respectively connected to the fixed ring 9 and the slider 11. When the electrical connecting piece 13 and the electrical connecting recess 14 are not in contact (e.g. Figure 4 The two cannot be electrically connected directly, and the diameter of the electrical connector 13 is the same as the inner diameter of the electrical connector recess 14, so that the electrical connector 13 can be embedded in the electrical connector recess 14.

[0031] Specifically, a power supply 15 is fixedly installed on the wall-mounted box 2, and the power supply 15 is electrically connected to the electrical connector 13 and the electrical connector recess 14 respectively. A buzzer 16 is electrically connected to the top of the power supply 15.

[0032] With the above technical solution, when the four sets of electrical connection recesses 14 on the fixing plate 7 are in contact with the corresponding electrical connection pieces 13 (i.e., the electrical connection pieces 13 are embedded in the electrical connection recesses 14), the circuit between the power supply 15 and the four sets of electrical connection recesses 14, the four sets of electrical connection pieces 13 and the buzzer 16 is connected. At this time, the power supply 15 will supply power to the buzzer 16 to make it alarm. Moreover, the circuit can be connected when any set of electrical connection recesses 14 is in contact with the corresponding electrical connection piece 13, so that the power supply 15 can supply power to the buzzer 16. It should be noted that in the intelligent interconnection system, the staff can control the power supply 15 to cut off the power through the mobile phone interconnection, which is the existing technology.

[0033] Working principle: During the installation of this smart gas meter, the expansion sleeve 5 and expansion screw 6 can stably install the mounting base 3 on the wall-mounted box 2, thereby achieving the effect of indirectly installing the gas meter body 4. At this time, since the expansion screw 6 is stably installed on the expansion sleeve 5 (the expansion screw 6 passes through the mounting base 3 and the wall-mounted box 2), the end of the expansion screw 6 will abut against the sliding plate 11 inside the fixing cylinder 8. Figure 4 As shown, under the limiting effect of the fixing ring 9, the slider 11, after being resisted by the expansion screw 6, will compress the spring 12, causing it to deform. Therefore, the electrical connecting piece 13 at the other end of the insulating rod 10 is not in contact with the electrical connecting recess 14. That is, the circuit of power supply 15, electrical connecting piece 13, electrical connecting recess 14 and buzzer 16 is not connected. However, in the event of theft by criminals, when any set of expansion screws 6 is screwed out of the corresponding expansion sleeve 5, the expansion screws 6 will no longer resist the slider 11. That is, under the elastic restoring action of the spring 12, It will slide forward against the slider 11, thereby driving the insulating rod 10 to move horizontally in sync, and finally allowing the electrical connector 13 to be embedded in the electrical connector recess 14. At this time, the circuit between the power supply 15, the electrical connector 13, the electrical connector recess 14 and the buzzer 16 is connected, that is, the power supply 15 will supply power to the buzzer 16, causing it to produce a piercing buzzing alarm sound, thereby deterring illegal acts by criminals and achieving the effect of preventing dismantling and theft. As for disassembling the gas meter during normal inspection and maintenance, technicians only need to disconnect the power supply 15 through mobile phone interconnection, and the gas meter can be removed normally by removing the expansion screw 6.

[0034] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
